设置的UINavigationController的RootViewController的比init

如何设置的rootViewController的UINavigationController通过以外的方法initWithRootViewController ？

我想用initWithNavigationBarClass:toolbarClass:提供一个自定义工具栏我NavigationController，所以我不认为我可以使用initWithRootViewController 。

Answer 1:

您可以通过调用解决这个setViewControllers 。

像这样：

UINavigationController *navigationController = [[UINavigationController alloc] initWithNavigationBarClass:[MyNavigationBar class] toolbarClass:[UIToolbar class]];

[navigationController setViewControllers:@[yourRootViewController] animated:NO];

知识共享使用斯威夫特：

从比应用其他delegate.swift类改变根视图控制器

let appdelegate = UIApplication.sharedApplication().delegate as! AppDelegate
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
var homeViewController = mainStoryboard.instantiateViewControllerWithIdentifier("HomeViewController") as! HomeViewController
let nav = UINavigationController(rootViewController: homeViewController)
appdelegate.window!.rootViewController = nav

希望有人这样会很有帮助。

编辑：

更改RootViewController的动画可与实现：

 UIView.transitionWithView(self.window!, duration: 0.5, options: UIViewAnimationOptions.TransitionFlipFromLeft, animations: {
    self.window?.rootViewController = anyViewController
}, completion: nil)

我们可以写太相似了归纳法这一点。

这个工作对我来说，希望它可以帮助你，

let rootVC:LoginViewController = self.storyboard?.instantiateViewControllerWithIdentifier("LoginViewController") as! LoginViewController
let nvc:UINavigationController = self.storyboard?.instantiateViewControllerWithIdentifier("RootNavigationController") as! UINavigationController
nvc.viewControllers = [rootVC]
UIApplication.sharedApplication().keyWindow?.rootViewController = nvc

在SWIFT 3.0 xcode8.1

在常规设置中删除主界面：主< - 这个主界面后：

class AppDelegate...

 var window: UIWindow?

    fun application...

      window = UIWindow(frame: UIScreen.main.bounds)
      window?.makeKeyAndVisible()
      window?.rootViewController = UINavigationController(rootViewController: NewYourController)

Answer 5:

  let storyboard = UIStoryboard(name: "Main", bundle: nil)         
  let yourNewRootView = storyboard.instantiateViewControllerWithIdentifier("yourNewRootView") as? yourNewRootView


   self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

    UIView.transitionWithView(self.window!, duration: 0.1, options: [UIViewAnimationOptions.TransitionFlipFromRight,UIViewAnimationOptions.TransitionFlipFromLeft], animations: 
    {
        // animation

        }, completion: { (finished: Bool) -> () in

            self.window?.rootViewController = nil
            self.window?.rootViewController = yourNewRootView
            self.window?.makeKeyAndVisible()
    })
